  • any one of the engaging concave portion 63f1 provided in one stopper member 6f and the engaging concave portion 63r1 provided in the other stopper member 6r in the pair of stopper member 6f and 6r is engaged, thereby supporting the panel support member 5 so as to be tilted to a predetermined position.
  • the pair of stopper members 6f and 6r are provided with at least two each of the engaging concave portions 63f1, 63f2, 63r1 and 63r2.
  • the engaging concave portions 63f1/63f2 of one stopper member 6f is engaged with one lower horizontal member 22
  • the engaging concave portions 63r1/63r2 of the other stopper member 6r is not engaged with the upper horizontal member 21.
  • the panel support member 5 can be supported at tilted positions of at least four places, and the solar panel 7 can be supported so as to be tilted in accordance with the altitude of the sun in respective four seasons or wind resistance positions in a typhoon.
  • the stopper members 6f and 6r are provided with the engaging concave portions 63f1, 63f2, 63r1 and 63r2, and the shallow engaging concave portions 64f1, 64f2, 64r1 and 64r2 to be engaged with a portion not reaching a half circumference of the outer periphery of each the upper horizontal member 21 and the lower horizontal member 22 that are alternately arranged.
  • the engaging concave portions 63f1 or 63f2 of one stopper member 6f is engaged with the lower horizontal member 22 as one horizontal member
  • the shallow engaging concave portions 64r1 or 64r2 of the other stopper member 6r is engaged with the upper horizontal member 21 as the other horizontal member.

  • the rotational force works on the panel support member 5 in a direction in which weights on both ends with the rotation center SC interposed therebetween are balanced.
  • the weights are balanced when the panel support member 5 is in the horizontal position. Accordingly, when the operator intends to change the position of the panel support member 5 from a steep slope position to a gentle slope position, the panel support member 5 is naturally rotated to allow the horizontal member (the upper horizontal member 21 or the lower horizontal member 22) to be engaged with the engaging concave portions 63f2, 63r1 and 63r2 at a next engagement position of the gentle slope only by performing the operation of disengaging the engaged engaging concave portions 63f1, 63f2 and 63r2 of the stopper member 6f and 6r from one horizontal member (upper horizontal member 21 and the lower horizontal member 22).
  • a mount for a solar panel 101 according to the second embodiment differs from the first embodiment in a point that the position of the combined center of gravity G on which the total weight W of the panel support member 5, the stopper members 6f, 6r and the solar panel 7 acts is set so as to correspond to the rotation center SC as shown in Fig. 11 .
  • the same symbols are added and explanation thereof is omitted.
  • the position of the combined center of gravity G on which the total weight W of the panel support member 5, the stopper members 6f, 6r and the solar panel 7 acts corresponds to the rotation center SC of the panel support member 5 as described above. Accordingly, the panel support member 5, the stopper members 6f, 6r and the solar panel 7 are constantly balanced with respect to the rotation center SC. Then, whichever angle the panel support member 5 is supported at, the operator can change the panel support member 5 to a desired tilt angle without adding a large force. Other operations and effects are the same as those of the first embodiment, the explanation thereof is omitted.
  • a mount for a solar panel 201 according to the third embodiment differs from the first embodiment in a point that the position of the combined center of gravity G on which the total weight W of the panel support member 5, the stopper members 6f, 6r and the solar panel 7 acts is set in a position deviated to the front side of the rotation center SC as shown in Fig. 12 .
  • a rotational force works in a direction of biasing the tilt angle to a steep angle on the panel support member 5 to which the solar panel 7 is fixed (in Fig. 12 and Fig. 13 , the combined center of gravity G is expressed as a large deviation for making explanation easy to understand).
  • the same symbols are added and explanation thereof is omitted.
  • the panel support member 5 rotates in the counterclockwise direction in Fig. 12 , and the lower horizontal member 22 is disengaged from the shallow engaging concave portion 64f1 at the upper position in the front-side stopper member 6f. Then, the lower horizontal member 22 is engaged with the upper engaging concave portion 63f1 as shown in Fig. 13 . At that time, the upper horizontal member 21 is engaged with the shallow engaging concave portion 64r2 at the lower position in the rear-side stopper member 6r. Accordingly, the panel support member 5 is supported at the tilt angle of 30 degrees.
  • the operator when the tilt angle of the panel support member 5 is changed to a steep angle, the operator can change the tilt angle to a next tilt angle position only by disengaging the engaging concave portions 63r1, 63r2 or 63f2 of the stopper members 6f and 6r engaged with the upper horizontal member 21 or the lower horizontal member 22.
  • the combined center of gravity G on which the total weight W of the panel support member 5, the stopper members 6f, 6r and the solar panel 7 arranged and fixed to the panel support member 5 acts is set to be deviated to a side to be lower by tilting when the panel support member 5 is rotated.
  • the rotational force of rotating the panel support member 5 in a steeper direction works on the panel support member 5. Accordingly, when the position is changed from the gentle slope position to the steep slope position, the panel support member 5 is naturally rotated and allows the one horizontal member (the upper horizontal member 21 or the lower horizontal member 22) to be engaged with the engaging concave portions 63f1, 63f2 and the 63r2 only by performing the work of disengaging the engaged engaging concave portions 63f2, 63r1 and 63r2 of the stopper members 6f and 6r from the other horizontal member (the upper horizontal member 21 or the lower horizontal member 22).
  • a mount for a solar panel 301 according to the fourth embodiment differs from the first embodiment in a point that a gravity-center position moving device 8 is provided in the panel support member 5.
  • a gravity-center position moving device 8 is provided in the panel support member 5.
  • the gravity-center position moving device 8 includes a guide rail 81, a weight 82 as a weight part sliding along the guide rail 81 and a positioning stopper (not shown) for holding a position of the weight 82 on the guide rail 81.
  • the guide rail 81 is provided so as to extend along a longitudinal direction of the rotating bar member 51R on a side surface of the rotating bar member 51R of the panel support member 5.
  • the guide rail 81 extends over both sides of the front side (corresponding to one side) and the rear side (corresponding to the other side) of the panel support member 5 with the support shaft 4 interposed in the center (rotation center SC).
  • the guide rail 81 is formed of, for example, a stainless steel material formed in an H-shape in cross section, in which engaging grooves (not shown) extending along the longitudinal direction are provided on both side surfaces. A back surface of the guide rail 81 is fixed to the side surface of the rotating bar member 51R.
  • the weight 82 is formed in an approximately rectangular parallelepiped shape, in which engaging projections (not shown) to be engaged with the engaging grooves on the side surfaces of the guide rail 81 respectively so as to slide are provided in an upper part and a lower part on a back surface side.
  • the weight 82 is stopped at a front-side position F, a central position O and a rear-side position R on the guide rail 81 by the positioning stopper operating by the operation of the operator.
  • To move the weight 82 from the front-side position F to the central position O, and from the rear-side position R to the central position O correspond to the approach to the rotation center SC.
  • To move the weight 82 from the central position O to the front-side position F or the rear-side position R corresponds to the separation from the rotation center SC.
  • the operator positions the weight 82 to the front-side position F by the gravity-center position moving device 8. Accordingly, a rotational force rotating toward the steep tilt angle is generated in the panel support member 5, and the panel support member 5 rotates to the tilt angle of 20 degrees steeper than the current angle only by releasing the engagement between the engaged engaging concaving portion 63f2 and the lower horizontal member 22.
  • the operator positions the weight 82 to the central position O or the rear-side position R by the gravity-center position moving device 8. Accordingly, a rotational force rotating toward the gentle tilt angle (0 (zero) degree) is generated in the panel support member 5, and the panel support member 5 rotates to the tilt angle of 0 (zero) degree gentler than the current angle only by releasing the engagement between the engaged engaging concaving portion 63f2 and the lower horizontal member 22 in the front-side stopper member 6f.
  • a gentler tilt angle for example, 0 (zero) degree
  • a tilt angle for example, 10 degrees
  • the operator positions the weight 82 in the front-side position F by the gravity-center position moving device 8.
  • the operator positions the weight 82 in the central position O or the rear-side position R. Accordingly, the operator can change the tilt angle of the panel support member 5 easily without performing complicated operations in which the end portion of the panel support member 5 is pulled up or pressed down.
  • the panel support member 5 is provided with the gravity-center position moving device 8 capable of moving the position of the combined center of gravity G to any of one side or the other side of both sides with the rotation center SC interposed therebetween by allowing the weight part (weight 82) to be close to or away from the rotation center SC.
  • the direction of the rotational force acting on the panel support member 5 is operated by moving the position of the combined center of gravity G by the gravity-center position moving device 8.
  • the panel support member 5 can be rotated in a necessary rotation direction to be changed to a desired tilt angle easily without rotating the panel support member 5 manually by the operator.
  • the gravity-center position moving device 8 is provided in the central position of the rotating bar member 51R of the panel support member 5 in the above embodiment, the present invention is not limited to this.
  • the gravity-center position moving device 8 may be provided at an end portion on one side of the panel support member 5.
  • the balance of the panel support member 5 is set so that a side where the gravity-center position moving device 8 is provided ascends when the weight is positioned to be close to the rotation center's side, and so that the side where the gravity-center position moving device 8 is provided descends when the weight is positioned to be away from the rotation center.
  • the stopper members 6f and 6r are supported so that upper portions rotate freely, which are arranged so that undersurfaces of the long plate-shaped portions abut on the horizontal members in the tilted state. Then, the engaging concave portions are engaged with the horizontal members due to own weights of the stopper members.
  • the present invention is not limited to the structure in which the stopper members rotate due to own weights, and for example, a spring member for biasing the stopper member to a rotating direction may be provided.
  • the present invention can be applied to solar panel facilities in which the tilt angle of the solar panel is required to be changed many times or frequently.
